Kris Boyd is considering an offer from Major League Soccer side Houston Dynamo, according to Sky Sports News sources.
The former Rangers and Middlesbrough striker has also attracted interest from three English clubs since he terminated his contract with Turkish club Eskisehirspor last month.
Boyd launched legal proceedings against Eskisehirspor for alleged loss of earnings and, sources say, he is seriously considering a 'very attractive offer' from the MLS Cup finalists.
Houston Dynamo lost to LA Galaxy in the MLS Cup in November.
It's believed the Scottish Premier League's all-time highest goalscorer, and former Rangers striker, is not currently in discussions with Celtic.
